Exploitation Of Microorganisms

Microbiology may be described as one of the younger sciences with its history, as a precise subject, only dating as far back as Pasteur in the mid 1800s and his revelation both of the role of microorganisms in nature and their importance to human welfare. Medical scientists rapidly took up the challenge, with their area of microbiology flourishing and expanding almost in complete isolation from the rest of biology. We now know, of course, that microorganisms have always played an important, if not essential role, in the biosphere with fermented foods and beverages, plant and animal diseases and nutrient cycling foremost in their sphere of activities. Within the last twenty years, microbiology has received two enormous boosts with the developments in microbial genetics and genetic engineering probably being the most influential, and the greater awareness of pollution and environmental sustainability following a close second. In 1990, your editor had the privilege and pleasure of being elected as President of The Association of Applied Biologists in the United King dom and, as the topic for his three-day Presidential Conference, chose 'The exploitation of microorganisms in applied biology'. This meeting stimu lated great interest in a wide range of subject areas, from weed control to nematology, from plant breeding to plant pathology, from mushrooms to mycorrhiza. The proceedings of this meeting were published in Aspects of Applied Biology, No. 24, 1990.

This book embodies 21 review articles contributed by subject experts of various areas of industrial microbiology. The articles are devoted to pharma industries, food and enzyme industries, textile industry, agro-industry and cottage industry. Yeast is one of the important microorganisms which have been used to produce beverages, alcohols and fermented food commodities for a very long time. In recent years, it has been the first choice among eukaryotes to use in recombinant technology. Yeast and Spirulina are being used and marketed as Single Cell Protein (SCP). Mushrooms have been used by humans down the ages. In addition to a rich source of mycoprotein, they have medicinal values also against many ailments. Number of bioactive novel compounds is increasing with the discovery of microbial species and newer groups of microorganisms. Some chapters are devoted to microbial bioinoculants used as biofertilizers because they are rich source of nitrogen and phosphorus for both legumes and non-legumes. They are being manufactured and sold in market with different trade names. In addition, several microbial enzymes have been produced and commercialized by various industries, but highly active and potential enzymes produced through recombinant DNA technology hold much importance. For example, microbial proteases find application in detergent leather, food and pharma industries and provide eco-friendly technology for bioremediation. Laccase has been worked out to be a good tool for bioremediation of non-degradable wastes and xenobiotic chemicals. Besides, laccase-based biosensors have also been constructed which can be used for phenol determination, monitoring of lignin and plant flavonoids. Various microbial phytases as feed supplemented have been used in freshwater and marine aquaculture for improving the growth performance of fishes. Nowadays aquaculture is growing rapidly to meet increasing food demand throughout the world for high quality fish. More than 16,000 bioactive compounds have been isolated from actinomycetes alone including antibiotics, enzymes, vitamins, amino acids, siderophores and nanoparticles. Biosynthesis of nanoparticles by bacteria, actinomycetes and algae has been reported and work is being done nationally and internationally.

Microorganisms are ubiquitous and indispensable for the existence of mankind. They show diversity in size, shape, metabolism and the range of positive functions they perform for sustaining the life on this planet. Bacteria have been exploited by the mankind since times immemorial for the production of various foods and enzymes. They reveal several types of metabolic reactions which are absent in eukaryotic organisms. The present book highlights the potential of microorganisms in solving the global energy crisis. Presently, the world is facing energy crisis due to depleting fossil fuels which are expected to get exhausted during the next 50 yeaOne of the alternative energy resources for the new millennium is expected to be the renewable energy including biomass from which a variety of biofuels can be obtained by the exploitation of microbes. This volume has been organized in 13 chapters which have been prepared to provide the readers with both an in-depth study and a broad perspective of microorganisms for sustainability of mankind. Further, it makes the readers familiar with the diversity in energy generating pathways among different groups of microorganisms and different types of biomass energy resources available on this planet and the various possibilities which can be exploited for converting these in to alternate energy sources with the help of microbes. A great effort has been made to provide the readers a comprehensive knowledge about different alternative fuels and value added products from microbes for the 21st century. It is hoped that this volume will prove useful to the students and professionals who are pursuing their career in Microbiology, Biotechnology, Biochemistry, Environmental sciences and Energy studies related to the alternate biofuels to solve the global energy crisis.

Over the last few decades, the rapid and vast development of advanced microbial bioresources and metagenomics techniques has completely transformed the field of microbial biotechnology. Our understanding of microbial diversity, evolutionary biology, and microbial interaction with their animal and plant hosts at molecular level has been revolutionized with an abundance of new research. This new volume, Advances in Microbial Biotechnology: Current Trends and Future Prospect, focuses on the application of microorganisms for several purposes: for plant protection and improvement, for environmental remediation purposes, and for the improvement of human health. Various applications of microorganisms are covered broadly and have been appropriately reflected in depth in different chapters. The book is divided into four major sections: applied microbiology in agriculture microbes in the environment microbes in human health microbes in nanotechnology The book provides insight into the diverse microorganisms that have been explored and exploited in the development of various applications for agricultural improvements. The book also looks at the application of microbes for the removal of pollutants and the recovery of metals and oils. Also discussed is the detection and exploitation of microorganisms in the diagnosis of human diseases, providing possible holistic approaches to health. This new volume will provide a wealth of information on new research on the application of microbial biotechnology today.

The field of microbiology and biotechnology are intertwined since time immemorial however the ties between the two areas became prominent in the last century. The areas provided various products which enriched mankind in various ways mainly in the form of food and succeeded in producing medicines. There was no technology which provoked the humans to understand the mechanisms involved whilst using microbes. In previous millennia, microbes were utilized by humans for several needs; however there was no scope of understanding the machinery to the complete detail.The nineteenth century bore an outstanding scientist named Louis Pasteur who pioneered in industrial microbiology. His understanding of microbes laid a path to the other discoveries which made human life more comfortable and also increment in life span is clearly noticed. The fight against infectious diseases has progressed with the advancements in microbiology. The era of mass production of the microbial products initiated mainly with citric acid production. The Second World War provided an essentiality to understand the process of preservation of products in aseptic conditions.The economically viable products such as vaccines, cytokines, pharmaceuticals and foods were produced in a large scale due to advancements in genetic engineering in the seventies. The applied microbiology and biotechnology are playing a crucial role in dictating national economy, medicine, agriculture, environmental protection and pharmaceuticals. The main reason to devise this part of literature is to introduce and summarize the current state of knowledge which concerns microbial application in large scale production lines. This book is built on my experiences with several research fronts during these two decades.The field of industrial microbiology and biotechnology deals with exploitation of microbes is a systematic manner in order to obtain goods and services for human welfare. The two immediate aspect of industrial microbiology are fermentation processes and service delivery especially in pollution control. It is assumed that the reader may have got some learned experience in microbiology to understand this book. The students of any life sciences and chemistry can understand the concept delivered in this book without any hassles.The application of microbiology in industrial biotechnology is broadly emphasized in this book. The chapters were designed to let the reader take a systematic study without getting struck at any concept and never feel confused.I would like to express my gratitude to all the professors and researchers who provided me variety of inputs to make this literature work a success. All the valuable time they invested in me to bring out this book is duly appreciated and some of the reflections which they expect are in due till the book is read by many of the enthusiastic students.
